City Cranes
The city crane is a small 2-axle mobile crane which is designed to be utilized in tight areas where other cranes could not go. The city crane can work in between buildings and could travel through gates. In the 1990s, City cranes were developed as a solution to the growing urban density within Japan. A lot of cities in the country began building and cramming more structures in close proximity and it became necessary to have a crane that was capable of navigating through the small roads in Japan.
Essentially, the city crane is a small rough terrain crane. This crane is designed to be road legal and is characterized by a short chassis, a single cab, the 2-axle design and independent steering on each axle. Moreover, these equipments offered a retractable slanted boom. This kind of retractable boom takes up a lot less space than a horizontal boom of the same size would.
Standard Truck Crane
Mobile cranes with a lattice boom are considered standard truck crane booms. This model has a lighter boom on a hydraulic truck crane. There are multiple boom sections that could be added to enable the crane to reach over and up an obstacle. A standard truck crane requires separate power to be able to move down and up, because it could not raise and lower using hydraulic power.
Kangaroo Crane
A jumping crane is another name for a kangaroo crane. This unit is an articulated-jib slewing crane with an integrated bunker. These cranes originated in Australia. They are often used in high-rise construction projects. Kangaroo cranes are different in the business in the way that they could raise themselves as the building they are working on increases in height. These specific cranes are anchored utilizing a long leg. This leg runs down the building's elevator shaft.
